Abstract
A PCMCIA card includes a processor and a dual-ported memory thereon. The PCMCIA card is plugged into a host, such that both the PCMCIA card's processor and the host have access to the dual-ported memory. Upon initialization, the host will load the dual-ported memory will a boot sequence for the processor on the PCMCIA card. The processor on the PCMCIA card is then released from a reset state, and proceeds to boot from the boot sequence loaded by the host. The processor on the PCMCIA card is released from reset by the host accessing a predetermined location within the address space of the PCMCIA card.
